It is good to be educated about how long to wait if you have improper shot placement. But, personally, I don't feel anyone belongs out there hunting unless they are postive that they know how and where to shoot an animal. PRACTICE, PRACTICE, PRACTICE. I understand that even with practice nerves can take over especially if you get the shakes. If you have an accident and get bad shot placement on an animal then give that animal some time. 4 to 5 hours seems to be the time limit most think works.Good luck out there, happy hunting!
